Texas solution or nuclear nightmare? : as a company in the Lone Star State moves to profit from America's dilemma with spent nuclear fuel, others fear the worst [PDF]

open access: yes, 2015
textThe United States government has sought a permanent disposal site for spent nuclear fuel since 1982. To date, no location for disposing of spent fuel exists.

Black shale deposition during the Early Jurassic: Geochemistry of Pliensbachian and Toarcian sedimentary rocks of the Hunzen Well, Hils Syncline, Northwest German Basin

open access: yesThe Depositional Record, EarlyView.
Our research uses a multidisciplinary approach, including organic and inorganic geochemistry, biostratigraphy, carbon isotope geochemistry and organic petrography to reconstruct depositional conditions and organic matter accumulation during the Pliensbachian and Toarcian.

Gas migration at the granite–bentonite interface under semirigid boundary conditions in the context of high‐level radioactive waste disposal

open access: yesDeep Underground Science and Engineering, EarlyView.
A series of water infiltration tests and gas permeability tests were conducted on granite and granite–bentonite samples. According to the results, the interfaces between granite and bentonite and the damaged granite were considered to be the preferentcial pathway for gas migration.

Thermal Conductivity of Korean Compacted Bentonite Buffer Materials for a Nuclear Waste Repository

open access: yesEnergies, 2018
Engineered barrier system (EBS) has been proposed for the disposal of high-level waste (HLW). An EBS is composed of a disposal canister with spent fuel, a buffer material, backfill material, and a near field rock mass.

Elevated temperature effects on swelling pressure of compacted bentonite

open access: yesDeep Underground Science and Engineering, EarlyView.
We present a set of new experimental investigations on the effects of elevated temperature on the swelling pressure development of compacted bentonite. This research was motivated by an emerging interest in using bentonite as a plug material in oil and gas well abandonment.

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Hydraulic Conductivity of Geosynthetic Clay Liners to Low-Level Radioactive Waste Leachate

open access: yes, 2016
Hydraulic conductivity was evaluated for eight commercially available geosynthetic clay liners (GCLs) permeated with leachate characteristic of low-level radioactive waste (LLW) disposal facilities operated by the U.S. Department of Energy (DOE).
